    Default Save Textfield to an Array

    I have a crossword generator project, and the user is going to list in their words in text fields to generate a crossword puzzle from those words.
    I need to write a proper code to take in the words from the textfields and save them in an array.
    and then save them to a text field. to make it easier for the user to look at his word when he comes back to the application.
    I wrote A code, but it doesnt seem to be appropriate because everytime I try to print the array contents it prints nothing.
    I might need help with the line that takes the text from a text field and saves it in an array , or a new idea to do it.
    I am new to java and not very fimiliar with it.

    I am using Netbeans IDE

    Hello NorahPoly!
    Can you post the code you are having trouble with? Or better yet, a simple program that executes and shows the problem?

    this is my code that takes words from everytext field and save it to an array and then write it to a file, but it doesnt work.

    String[] words = null;// = new String[15];

    private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
    words[0] = word1TXT.getText();
    words[1] = word2TXT.getText();
    words[2] = word3TXT.getText();
    words[3] = word4TXT.getText();
    words[4] = word5TXT.getText();
    words[5] = word6TXT.getText();
    words[6] = word7TXT.getText();
    words[7] = word8TXT.getText();
    words[8] = word9TXT.getText();
    words[9] = word10TXT.getText();
    words[10] = word11TXT.getText();
    words[11] = word12TXT.getText();
    words[12] = word13TXT.getText();
    words[13] = word14TXT.getText();
    words[14] = word15TXT.getText();

    try
    {
    PrintWriter pr = new PrintWriter("blabla");

    for (int i=0; i<words.length ; i++)
    {
    pr.println(words[i]);
    }
    pr.close();
    }
    catch (Exception e)
    {
    System.out.println("No such file exists.");
    }
    }

    What is written to the file when the program executes?

    Are there any error messages?
    You should add a call to printStackTrace in the catch block to give a full error message.
    catch (Exception e)
    {
    System.out.println("No such file exists.");
    e.printStackTrace();  //<<<< give full error message with this
    }

    I'm going to assume you are using the Swing API? If yes, then JTextField has an inherited getText() method that returns a String.

    What kind of array are you wanting to save it to? A String is already an array of characters by default.
